The ConcreteMan Triathlon is the oldest Triathlon in Missouri. Started in 1982, the ConcreteMan became a staple multisport event in Missouri for years. The event when through many iterations over the years and included the sprint distance, olympic(ish), and at one point an open water swim. In 2023 we are excited to have revived the Historic ConcreteMan (in 2021) in aid of our mission to revitalize Multisport in the area. Join us for the 35th annual ConcreteMan Triathlon!
